To all irrhon'l/ it nmg concern.-

Be it known that 1, CHARLES ll. NUNN, a citizen of the United States, residin at Rochester, in the county of Monroe and State of New York, have invented certain new and useful lnnn-(wcnu-nits in. Oil-Cups; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, retcrence being had. to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in that class of oil-cups or lubricators which are designed for use upon engines and other machinery, whereby a by the opening and closing of a valve the dew of the oil may be regulated.

The invention has for its objects to provide an oil-cupof this class which will be so 0011- structed as to admit of the use of either light or heavy oils, and which will operate with the same reliability when in either a stationary or a moving position, which may be quickly and easily filled, and in which the feed may be adjusted at will.

To these ends and to such others as the invention may pertain the same consists in the peculiar combinations, and in the novel construction, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the accompanying drawings, and then specifically defined in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure 1 is a side view of an oil-cup con structed in accordance with my invention. Fig. 2 is a vertical central section of the same.

Reference now being had to the details of the drawings by letter, A designates the cylinder or body of the cup, which may be constructed of either glass or metal, and may be of any suitable and well-known form of 0011- struction.

B is a cap or cover for the oil-chamber. This cover is provided with one or more filling-apertures, O.

B is a supplemental cover surrounding the raised central portion of the cap B. This cover is provided with a handle, B", and serves when properly turned to close the filling-apertures C in the cap.

I) is a hollow tube passed centrally through the central portion of the chamber, and is provided near its lower end with one or more openings, (1, for the admission of the oil to the tube. It for any reason it should be thought desirable, the tube D may be cast integral with the cap. This construction I have shown in Fig. 2 of the drawings. The lower end of this tube D, which terminates within the central portion of the base E,is narrowed or contracted, as shown, and a glass-covered peephole is provided in the base E, through which the flow of the oil may be observed. The plug E is cast integral with the base, by means of which and of the screw-thread thereon the cup may be secured in place.

The upper end of the tube D is extended through the cover B,and is screw-threaded.

F is the valve-stem, the lower end of which is provided with a taper corresponding with that of the lower end of the tube, and the upper end of the stem is provided with a suitable cap or operating-button, F which is adapted to be screwed down over the upper end of the tube D. The lower edge of the cap F is in the form of a cam, as shown, and this cam-surface is provided with a series of notches, as shown at G.

G is a vertically-operating spring-actuated catch seated within a suitable chamber, G formed upon the lower face of the cover B. This catch is forced upward and is held nor mally in a raised position. by the tension of the spiral spring (Z within the chamber G The cap or button F is provided with a roughened or serrated edge to facilitate its being operated. The position and arrangement of the notches provided upon the depending lower cam-edge of the cap are adapted to engage the upper end of the spring-actuated catch G and are so graduated as to admit of a flow of a predetermined amount of oil to the bearings within a specified time, this predetermined amount being indicated by figures or characters arranged in the form of a scale upon the periphery of the cap above the notches, asshown.
